JOHN IVEIR, OF NEW YORK, N. Y.

MODE 0F RAISING AND LOWERINGVENETIAN BLINDS.

Specification of Letters Patent No. 1,807, dated October 8, 1840.

To all whom, may Concern.'

Be it known that I, JOI-IN WEIR, of New York, in the county and State of New York, have invented a new and Improved Mode of Raising and Lowering Venetian Window- Blinds; and I do hereby declare that the following is a full and correct description.

rIhe nature of my invention consists in the cords that suspend the blind Winding around a circular body, see drawing Figure l (in place of pulleys formerly used), the same cylinder or roller having a ratchet wheel and catch at one end, see Fig. 2, and said catch having a lever with a cord attached, to relieve it from the wheel at pleasure, and retarding it at any height required, see Fig. 3, the raising is performed by a cord winding around the end of the roller in a reverse way to those suspending the blind, see F ig. l, thus enabling a person to raise or lower the blind without the trouble of Xing the cords as formerly, to keep the blind at any height required.

That I cla-iin as my invention, and desire to secure by Letters Patent, is-

The mode of raising. and lowering Venetian lblinds and retaining them at any height without the operation of fixing the cords by means of the combination of the blinds, co-rds passing through the slats, the roller, the barrel on the end of the roller, and the cord passing around the same, and the ratchet wheel and catch, all as herein described.
